I don't have much to add to what's already been listed, but I do LOVE leftover ham!

My favorite post-Easter recipe is Royal Scallop (and if you google it, a bunch of different variations come up in old cookbooks.) My grandma always made it. It's diced ham and diced hardboiled eggs in a white sauce (my mom always puts a touch of dijon mustard in the sauce, yum) and served over baked potatoes. I crave it every spring!
